Hi patrickphillipsdotnet,
I'm sorry to hear about this, it's none of our intention for this to happen and definitely this is not the experience we want for you. Regarding the issue on how to disable Cortana. We thanks for the feedback you have provided. Once we have the solution for this we will circle you back
For the meantime, regarding with disabling Cortana on your headphone, you can directly connect it to Bluetooth so that the Cortana Features will not become as its function. However, all of the Cortana command or features will be disabled as well. To set up your headphone directly to Bluetooth, please follow this steps. Or you may check under Cortana to manage your Cortana feature.
You can review and control exactly what personal information Cortana can access by clicking into the search box and selecting Settings on the left pane. You can also search "Cortana settings" in the search box on the taskbar, and select Cortana & Search settings from the results.
First pair your headphones:
- Press and release the power button quickly to turn on your headphones—they'll be pairing mode the first time you turn them on.
Note
If you've previously paired your headphones with another device, press and hold the power button to put them into pairing mode. You'll hear a message saying they're in pairing mode, and the LED light will flash white. 2. Select Start > Settings > Devices > Bluetooth & other devices > Add Bluetooth or other devices> Bluetooth. 3. Select Surface Headphones and then select Done.
Thank you,
Christopher
